Might need to post this in the Alternative Energy forum.... My Trace C40 Charge controller has died... I've disconnected it from the system, and opened it up and can't find any fuses or user exchangeable parts... Anyone have any experience? Good or bad? New ones are pricey... of course, without it, my system will overcharge the batteries and boil em away, unless I monitor them continously, which isn't going to happen...since I'm currently On the grid.
